App1ication filed December 12 1912, Serial No; 736,276. Renewed January 21, 1915. Serial No. 3,633;

To all whom it mayconcem Be itknown that T,ULYssns hicQ'unnn, acitizen of the United States, and a resident, of the city, county, and, Stategof New.

York, have invented a new. and useful Im provement in Sash-Pulleys, of which the following is a specification.

Heretofore when three sashes have been hung side by side so as to form a triple window, and the weights have been suspended in wells at each side of the windows but not between any two of them, it has been necessary to fix some of these pulleys in the window frame before the same is inserted in a building, with the result that when a pulley became broken or otherwise injured so as to be unfit for use, it has been impossible to repair or renew the pulley without mutilating the frame or the buildlhe object of my invention is to provide a pulley which can be either inserted or removed after the frame is in place, and after the building is otherwise complete, so as to in no way interfere with the frame or other parts of the building when the pulleys and sashes are inserted. This object is accomplished by my invention, one embodiment of which is hereinafter set forth.

For a more particular description of my invention, reference is to be had to the accompanying drawings, forming a part hereof, in which 7 Figure 1 is asectional view of, a frame provided with my improved pulley; Fig. 2 is a plan view of the structure shown in Fig. 1; Fig. 3 is a side elevation of my improved pulley in its detached condition;

and Fig. 4 is a plan view of the structure shown in Fig. 3.

Throughout the various views of the drawings, similar reference characters designate similar parts.

In Fig. 1 is shown the left-hand side of the upper portion of a frame, in section, of

a triple window, the other corner being symmetrical therewith, so that a description of one will answer for both. The

frame 1 is placed below a lintel (not shown) and is provided with four wells, 2, 3, 4 and 5, in which suitable sash weights 6 are hung by chains? and 8, or other suitable means.

These chains 7 and 8 pass over suitable pul leys 9 and 10,'both of which are mounted in the top of the frame 1, the pulley 10 being afdouble pulley, that is, a pulley with two sheaves mounted on a. single spindle, so that onelend of the chain 8 can go over one sheave and the other, end over the other,

with the result that one weight can balance a sash. The chain 7 balances only half a sash, and so runs over a single sheave 11 mounted on a spindle 12 in the casting or hood 13 of the pulley 9. The casting 13 is provided with a suitable base 14 with'an interior slot 15, into which extend suitable form a recess which will enable this hood or casting to get close to the pulley 10 without interfering with the same.

From the foregoing the use and operation of my improved pulley will be readily understood. When the sash frame is built, suitable mortises are made for the pulleys 9 and 10 and the other pulleys (not shown), and suitable openings are made for the chains. The base 14. for each pulley 9 isalso inserted in place and secured by suitable screws 19 passing through perforations made for the purpose. When the sash frame is in the building and ready for use, a casting or hood 13 for each base 14 with its sheave 11 mounted on a spindle 12 is passed through the opening left for the pulley 10 and shifted until the flange 17 engages the lugs 16 and is shoved home so that the base 1 1 securelv holds'this casting or hood 13. The chain 7 and the parts connected therewith are then put in position,

the chain passing around the sheave 11 and that it is not restricted thereto, but is broad enough to cover all structures that come within the scope of the annexed claims.

portion extending into said base, said hood and base being so connec'ted that the hood may be slid in or out of the base froin one end of the base.

In testimony whereof I have signed my name to this application in the presence of two subscribing witnesses this 3rd day of ULYSSES G. MCQUEEN. 7 Witnesses:
